Menus, submenus, tooltips, rich tooltips and the FAB menu held their exit with `transition-behavior: allow-discrete` on `display` and `overlay`. Firefox transitions neither (MDN browser-compat-data, `display.is_transitionable`: Chrome 117, Safari 18, Firefox none), so every one of them vanished on its first frame there. A script cannot hold a popover open instead: `beforetoggle` is not cancellable on the way out, and the browser's own light dismiss (Escape, a press outside) never asks. resources/js/popover-exit.js: a popover marked `data-md-popover-exit` closes for real at once — focus, aria-expanded and toggle stay the browser's — and a copy taken in `beforetoggle`, while it is still drawn, stands in for the exit. The copy is decoration: a manual popover in the top layer (closing no other popover), inert, aria-hidden, without ids or nested popovers, `x-ignore`d so Alpine starts nothing in it, pinned to the popover's box with its resolved colours. It is shown with its transitions off, so `@starting-style` does not replay the entry, then marked `data-md-popover-closing`, which each stylesheet turns into its closed values (`:popover-open:not([data-md-popover-closing])`, and the FAB menu's items' sink), so it moves on the component's own tokens. It is removed once the longest of them has run, and opening the popover again takes it away. Under reduced motion every duration is zero and no copy is made. `display`, `overlay` and `allow-discrete` leave the transitions, so Chrome and Safari take the same path. Browser tests in Chrome, Firefox and Safari slow the motion tokens so a round trip still finds the exit on screen: a menu after Escape and after a press outside (the real menu closed and focus back on its button, the copy inert, fading, with no Alpine state, and gone after), a reopen part-way through, reduced motion, a submenu while its menu stays open, a tooltip, the FAB menu's items part-way down their sink, and a persistent rich tooltip.

/*
|
|
* <x-rich-tooltip>: an M3 rich tooltip, a few lines of context for a control, with an optional
|
|
* subhead and actions.
|
|
*
|
|
* RichTooltipTokens (androidx Compose Material 3, Apache-2.0): surface-container, the medium
|
|
* corner, elevation 2, 312px wide at most, 16px either side, 12px above the subhead (or the text
|
|
* when there is none) and 8px below it. Title-small subhead and body-medium text in
|
|
* on-surface-variant, label-large actions in primary — the actions row pulls itself back 12px to
|
|
* the text's edge, as the alert's actions row does (alert.css).
|
|
*
|
|
* Placed by CSS anchor positioning on `data-md-side`, corner-to-corner so the 312px bubble has
|
|
* room to spread past a narrow trigger; `position-try-fallbacks` flips it when the window has no
|
|
* room, same shape as tooltip.css's plain tooltip. It fades in and out on the fast effects spring:
|
|
* `@starting-style` gives the fade in a start, and the fade out is its exit copy's
|
|
* (`data-md-popover-exit`, resources/js/popover-exit.js), which `data-md-popover-closing` turns
|
|
* back to the closed opacity.
|
|
*
|
|
* resources/js/rich-tooltip.js shows and hides the bubble and keeps the trigger described with
|
|
* `aria-describedby` — and, while `persistent`, `aria-haspopup`/`aria-expanded` (ACT-22) — none of
|
|
* which this stylesheet draws.
